btrfs/295: skip on zoned device as we cannot corrupt it directly

We use _pwrite_byte to corrupt the root node, but such overwrite won't work
on a sequential write required zone. So, skip the test on a zoned device.

Technically, we can run this test case by checking if the physical location
lands in a conventional zone. But, the logic should be no difference than
the regular mode and I don't think it's worth doing so.
